Panel set 1 watt (PM-111)

Bookmark and Share by v8.7
  • Potentiometer PM111 is a panel setting device for a maximum wattage ratting upto 1 watt.
  • PM111 has been specifically designed to have longer life, No discontinuity and smooth movement of shaft.
  • It has a feasibility to customize in several ways. Such as shaft modification, lug terminal arrangement, a vast range of ohmic value from 10 ohms to 30k ohms.
  • The capability of the company to produce a vast range of potentiometer is a USP on its own.
  • PM111 is being manufacture using high grade engineering plastic with ROHS and FR grade approval make it competent to compete in word market.
  • The Product can be made to Ingress protection upto IP65 and above on request.
  • PM111 has several other variants with model number V.R- 1G (Ganged Potentiometer), V.R-1S (Endless Potentiometer), V.R-1CT (4 wire potentiometer).


For best performance of PM111 below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) PM111 should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of potentiometer should be maintained.
3) For applications with extreme vibration please use lock nut assembly which is being supplied on the demand.
